High Nitrogen Explosives. Part 2. Dibenzo-1 ,3a,4,6a- Tetraazapentalenes andBenzo-1 2,3,4-Tetrazine-1,3-Dioxides

摘要

High nitrogen materials are sought as a potentially dense, powerful butinsensitive explosive and propellant ingredients. Elucidation of the structure and chemistry of dibenzo-1 ,3a,4,6a-tetraazapentalenes has continued, with particular attention to a putative C12N12O12 derivative initially prepared at the University of New Orleans. This research contributed substantially to identification of the actual o-quinone hydrate structure, and explanation of the apparently anomalous explosiveinsensitivity of the material. Synthesis of the novel 5,7-dinitrobenzo-1, 2,3,4-tetrazine-1,3-dioxide has been repeated, its structure has been confirmed, and preliminary evaluation of its explosive sensitivity has been completed.
